1 Proportion of cattle that had the variable category and were in the cluster e.g. 15.39% of cattle that had a bronchopneumonia lesion in the whole population were in the cluster 2.
2 Proportion of cattle in the cluster that had the variable category e.g. 28.68% of cattle in the cluster 2 had a bronchopneumonia lesion.
3 Proportion of cattle in the global population that had the variable category e.g. 3.53% of the whole population had a bronchopneumonia lesion.
Categories of supplementary variables are underlined. Categories are presented according to decreasing absolute value of v-test. Inf= infinite, AMI= Ante-Mortem Inspection.
